RUBBER-STOCK RACK.

i Application filed January This invention relates to racks and par ticularly to an improved rack for rubber stock and has for an object to provide a construction wherein the stock may be quickly and easily' inserted andremoved.

Another object of thei'nvention is to provide a rack for rubber stock wherein the parts are so formed that the'stock may be quickly inserted in the rack directly from the mill. Y l i A still further object of the invention is to provide an improved rack which will receive the hot rubber stock from the mill and will properly support the same without the use of soapstone.

Y In the accompanying drawings- Figure 1 is a sectional view through Figure 2, approximately on line 1`1.

Figure 2 Vis a side view of a rack, disclosing an embodiment of the invention.

Figure 3 is a sectional view through Figure 2, approximately on line 3-3. Figure 4 is a top plan view of a bracket showing certain features of theinvention. Figure 5 is a perspective view of the frame supporting one of the perforated plates illustrated in Figure 1.

Referring to the accompanying drawing bynumerals, 1 indicates a frame which may be of any suitable construction, preferably formed of four angle iron posts 2 with con necting angle iron braces 3 at the top and bottom. Preferably, there is no angle iron brace `3 across the top at the front, though there Vis one across the bottom at the front. The posts 2v at the rear areprovided with apertures for receiving the respective bolts 4: extending through the turned down ends 5 of the rear bar 6 of the vplate supporting frame 7. This frame 4is provided with a front bar 8 and side bars 9 and 10. Aplate -11Vis riveted or otherwise: secured to this frame and entirely covers the same, said plate being comparatively` thin and perforated. The frame 7 is of comparatively thick strips of metal while the plate 11 is comparatively thin but acts as a proper support for a load of rubber whichmay be mounted thereon. lAt the front, the frame 7 is vprovided with supporting feet 12 which i resty on the next lower plate l1 while the -feet 12 of the bottom frame rest .on the front angle bar 3. It will be noted also that the lowermostlfram'e 7 is provided with side angle bars 13 to which the respective ropes 14 `and 15 are connected. In constructing 15, 1925. Serial No'. 2,709.

the frame, the various supporting legs are so formed that in raising they prevent the frame from jumping and chattering. Also, in case it is desired to lower all the plates at one time, thisv construction of legs pre.-

vents the respective succeeding plates catch-y ing the next plate.

As `indicated in Figure 1, the various frames 7 are pivotally connected to the rear post 2 and normally remain in a horizontal position though they are adapted to be ele-v vated as shown in the upper part of Figure 1 preparatory to being loaded. The ropes or cables 14 and 15 are connected with suitable drums 16 and 17 which are rigidly secured to a shaft 18 and said shaft is provided with a removable crank 19 whereby theV cables may be wound on the drums at any time. y i

In use, the rack 20 is raised or run up to the top which trips all of the catches 21 and holds vthem out of the way as it continually bears against the same. In order to prevent the rack from moving downwardly again, the pawl 23 is caused to function which locks the parts against downward A movement until manually released. After the rack has been vthus raised, all ofthe plates 11 may then be raised to an almost vertical position by rotating the crank 19. Upon the rotationof this crank, shaft `18 will be rotated and in turn the respective drums 16 and 17 whereupon the cables 11i andV 15 will be wound on the drums and the plates swung to their upper position. As

soon as the plates have all been swung to their upper position, the pawl 23 is moved manually to Yan inoperative position while the crank -19 is being held stationary. The rack 20 is then quickly lowered whereupon the various catches 21 will immediately swing into operative position. When this v'has been done,`the crank 19 may be released. Tok release the various plates 1'1one at a time, the catch or pawl 23 is moved to an operative position as shown in Figure 1 andthen the crank 25 rotated suiiiciently to elevate. the rack 20 the proper distance for striking the lowermost catch 21 and swinging the same to a` disengaged position whereupon `the lowermost plate 11 will swing bygravity to a horizontal position. This action is repeated for each plate and may be done as rapidly as desired. Usually one plate is released and allowed t0 drop to horizontal position, after which, it is loaded with rubber and then a second plate dropped into posit-ion and loaded. This action is continued until all or as many of the plates are dropped as desired. In loading the rack, the rubber is preferably placed so as to prolject a short distance beyond the front edge whereupon in emptying the rack it 1s only necessary to grasp each piece of rubber and pull the same from the rack. To load the rack again, the same operation 1s repeated. In order that the rack 20- shall be limited in its downward movement, thevguiding bar 28 is provided with an oset or turned over end 2S at the bottom which acts as an abutment for limiting the downward movement of the rack.

From Figure 2 it will be noted that the shaft 24 is rigidly secured to the pinion'22 and extends to the front `of the machine where a crank 25 is secured thereto.k Connected by rivets or lothermeans with the rack 20 are guiding loops 26 and 27 which loosely fit around the vertical guiding bar 28 rigidly secured by a bolt or'other means at 29 to one ofthe bars 3 at the bottom o t the machine to a-brace Snear the center and to a bracket 30 at the top of the machine by a suitable bolt or rivet. The bracket 30 is substantially AU-shaped and is bolted or otherwiserigidly secured to the angle bar 31, which angle bar is riveted or vbolted tothe brace 3 and also to the top members 3.- Mounted on one face ot the angle bar 31 area number of catches 21 which are pivotally mounted on the angle bar by suit-able pins 32. These catches are merely short sections of a flat bar and prof vided with a weight 33 at one end and a beveled portion '34 at* the opposite end. When the. rack 205 is moved upwardly, the rear part of the rack bar will engage one end of the catches 2l and swing the catches to a substantially vertical position. After the cables 14 and l5 have swung all of the plates ll to a substantially*vertical position, they are held temporarily in that position by the cables and rack'20 is then actuated until it is moved to ,itsl eXtreme down position whereupon all of the catches 21 are released andwill automatically swing to a position whereby one catch will be in front of each of the `trames 7 c This will hold' all of the iframes in `their elevated position andwhen it is desired to use the irstframe and plate, rack .20 yis moved vupwardly until the first catch is swung to a vertical Vposition whereupon thelowermost frame and its plate will automatically Jfall to arsub'stantially hori zo-ntal position. A load of rubber is @placed on this plate and-'then rack 20 is againelevated a short distance'or untilthenext catch 2lL has been released whereupon the second plate ll Jfrom the bottom will be released andwill automatically drop to avhorizontal position. A load of rubber isv placed on this second plate or sheet 1l and a thirdl plate is allowed to drop. .This action 1s c0n' tinued until the rack is entirely loaded or tion and also readily lremoved as each piece of rubber is allowed to pro-ject slightly' yond the variousplates 1l.

\ Hereto'tore, racks have been provided with sliding supports but in the sliding structure it is necessary to slide the support out of position, loadthe same with rubber stock and then slide the same back into position. lll hen using the stock, a reverse action is necessary, while vin the present construction the respective supporting plates are dropped into position quickly and the rubber stock may be thrown into position easily. It will be seen from Figure 5 that the aper-v tures LL vare oifset fromlthe plane of the plate 11. This is Very desirable in that it Vwill `allow the various plates toV be raised to an almost vertical position as shown in the upper part of Figure 2 and occupy a minimum space.- The feet or legs-12 are beveled on one part whereby they permit the plates to be freely swungv upwardly or downwardly. It willpalso be noted thatthe legs or feet are formed with anoll'set member 35 positioned to make vit bear against the catch in a line parallel-to the catch and indirectly make the.. frame bear against the catch in a line parallel tothe catch. The catch is ablev to hold a 'substantial weight that is parallel to it but cannot hold a small weight that is pushing'at an angle and, consequently, the member 35 is essential tothe proper functioning of the catch to hold the platesin their raised. position.
